3 Claims.

This invention relates to coupling devices and particularly to a sub or connection used in bailing or cleaning wells.

At the present time, it is the practice when changing from a bailing operation to a swabbing operation or vice versa, to melt the Babbitt metal out of the rope socket and re-babbitt the swab line in the rope socket. This operation requires about two hours time.

The object of my invention is to eliminate the labor thus involved and the time required by providing a connection which may be readily connected to the bail of a bailer or disconnected therefrom, and which is also adapted to couple onto a rope socket and which, when in use, does away with the necessity of cutting the swab line and taking the rope socket off in changing from a swab to a bailer or sand pump.

A further object is to provide a connection of this character which will hold the bail of the bailer steady and in place.

My invention is illustrated in the accompanying drawing wherein:

Fig. 1 is an elevation of a connector or coupling constructed in accordance with my inven-' tion, the bailer being shown in section.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 3--3 of Fig. 2.

Referring to this drawing, I0 designates generally the body of my attachment or connecting coupling. This body isprovided at its upper end with upwardly tapering threads ll whereby it may be connected to a rope socket. Below the tapering threads, the body is formed with a cylindrical portion 12 upon which rotary tongs may be used in making up a well string. Below the cylindrical portion l2 there is a many-sided portion I3 upon which a cable tool wrench may be applied. Below this many-sided portion l0 there is a head l4 rectangular in cross-section which is formed in its lower face with an upwardly extending relatively wide and deep slot l5. This slot opens upon the ends of the head. The

upper wall of this slot is upwardly bowed longitudinally and this upper wall is transversely curved, as at I6. Adapted to be disposed within the slot I5 is a block I! which has an upwardly bowed upper face, this upper face being grooved at 18. The block has a length equal to the length of the head l4 and the ends of the block are flush with the ends of the head when the block is in place. The block is formed with a plurality of transverse passages IQ for the passage of bolts or screws 20. Preferably the attaching means is in the form of a screw threaded at one end for insertion in the screw threadedportion 2| of the passage l9 and preferably the exterior face of the block M is recessed or countersunk at 22 to receive the head of the bolt 2!].

The bail 23 of the bailer 24 has the form of an inverted U as usual, and this bail is adapted to fit within the slot l5 and to be held in place and supported by the block ll. It will be seen that this block holds the bail of the bailer absolutely steady and in place. By this means, it is an easy matter to connect the bailer to the rope socket at any time desired without the necessity of cutting the swab line and taking the rope socket off.

The present way of swabbing and bailing is to first babbitt the rope socket on the swab line. Then after swabbing has been completed, the line has to be cut in order to take the rope socket off of this line so as to connect the line on the bailer. After bailing is through, the line has to be out again in order to remove the kinks so that the line will go through the rope socket for use on the swab or sand pump. After the line has been cut from the rope socket, it is necessary to melt the babbitt out of the rope socket before this long line is re-babbitted in the rope socket. By the use of my connector, the line will never have to be cut. After swabbing has been completed, it is easy tochange over from the swab line to the bailer or sand pump without all the inconvenience of cutting lines and re-babbitting.

It is to be understood that this device is used during the bailing operation and when running the sand pump, but when changing back to the swab, this connector is left off. This connector provides a quick method of changing from swab over to the bailer or to the sand pump, without the necessity of cutting the line and doing a lot of babbitting. With this device, the line is left connected with the rope socket, babbitte'd in as it had been used in swabbing, and all that is required in making the change over to the bailer or sand pump is to screw this sub into the rope socket and then fasten it securely with the bolts, as shown in the drawing. The old method required from 1 to 2 hours of work, but by using this device, the change can be made in 5 to 10 minutes. It is to be understood also that if the eye in the sand pump will not fit the inserted block I'l, this block may be left off and the bolts 20 may be put through the eye of the sand pump. 50

What is claimed is:

1. A connector of the character described, comprising a body formed at its upper end with an upwardly tapered screw and at its'lower end with a head having a transversely extending slot 55 from end to end, the upper wall of the slot being transversely curved and being upwardly curved longitudinally, a supporting block fitting in said slot and having an upwardly bowed upper face complementary to the upper wall of the slot, said upper face being transversely grooved, the said block being of less length than the slot and positioned midway of the ends thereof, and a plurality of bolts passing through the head and through said block and detachably holding the block in place. 7

2. A connector of the character described, described, comprising a body formed at its upper end with an upwardly tapered screw and at its lower end with a head having a transversely extending slot from end to end, the upper wall of the slot being transversely curved and being upwardly curved longitudinally, a supporting block fitting in said slot and having an upwardly bowed upper face complementary to the upper wall of the slot, said upper face being transversely grooved, the block being of a length materially less than thelength of the slot whereby an arcuate body disposed in the slot between the, curved wall of the slot and the upwardly bowed face of the block will be secured against swinging movement transversely of the slot, a plurality of bolts passing through the head and through said block and detachably holding the block inplace, the body between the head and the screw being formed to provide a cylindrical portion to which tongs may be applied, and a many-sided portion for the application of a wrench.

3. A connector of the character described, including an elongated body formed at one end with a a longitudinally extending tapered screw and at its other end with a head having a transversely extending slot opening through the end face of the head and through opposite sides thereof, a supporting block fitted in said slot and having a length less than the length of the slot between the said opposite sides of the head, the block being disposed centrally between the said sides of the head, securing elements passing into the head and through said block to detachably hold the block in the slot, the slot and block having spaced opposed faces of arcuate curvature designed to form an arcuate passage in which an arcuate supported body may position.
